 Description   

All index types provide an implementation of getKeys() which, given a document and an index key pattern, return a set of BSONObjs representing the keys. For those index types that can have a non-simple binary compare collation, we need to change getKeys() to return BSONObjs containing collator-generated comparison keys for string elements.

The supported index types are:

  • btree version 1
  • 2d
  • 2dsphere
  • hashed
